- I want to know what can be possible output velocity when pressurised fluid passes through a convergent-divergent nozzle.
Suppose, there is a convergent-divergent nozzle where the inlet and the outlet both has 5 sq cm area while the throat has 1 sq cm area. A pressurised compressible fluid at 5 barA pressure having velocity 10 m/s entered the c/d nozzle. The back pressure i.e. the pressure at the outlet is 1 barA pressure. I want to know what can be possible velocity of the fluid at the outlet. My common sense and little understanding of nozzle properties tells me that the velocity is around 250 m/s.
